Tracking Shifting Sands Along the Nation's Coast

As New Yorkers braced themselves for Hurricane Sandy, coastal geologist Cheryl Hapke was out surveying Fire Island, a barrier island off the Long Island coast. Days later, Hapke was back to document the hurricane's effects and found a breach cutting the island in two. Now locals and scientists are debating whether the inlet should be filled in or left as nature intended.

Originally published on Fri July 12, 2013 8:37 pm

The "Giant Tabular Iceberg" floats in Antarctica's Ross Sea in December 2011. Under a proposed new international agreement, large sections of the oceans around Antarctica would become protected as a marine preserve.
